1964-1967 Pontiac GTO LS and LT 17.5 inch Tall Radiator for Manual Trans
Your project deserves a cooling system that mirrors the original layout while handling modern powerplant heat loads. This radiator is crafted for 1964 through 1967 Pontiac GTO manual trans setups with LS or LT engines and features a 17.5 inch core height that aligns with factory brackets and shroud positions without any trimming. Along with its corrosion resistant aluminum build and precise hose port alignment this unit ensures consistent coolant flow under spirited driving or stop and go traffic. Each example fits the A Body frame as a direct replacement so installation is straightforward even for first time swappers.
Seamless Integration with 17.5 Inch Core Height
This radiator preserves the factory 17.5 inch core height to fit 1964-1967 Pontiac GTO A-Body frames without altering brackets or shroud clearance. Precise hose port alignment ensures coolant hoses and fan assemblies follow the original routing, even when pairing modern LS or LT engines with a manual transmission. By matching the original dimensions, the unit installs cleanly and eliminates the need for trimming or custom fabrication. This approach maintains the stock appearance of the engine bay while delivering reliable coolant flow from day one. Enthusiasts benefit from a straightforward installation that respects the car's classic layout.
Lightweight Aluminum Structure for Rapid Heat Dissipation
Constructed from high quality aluminum, this radiator combines light weight with exceptional thermal conductivity to meet the heat rejection requirements of LS and LT powerplants in a vintage chassis. Aluminum's superior ability to transfer heat means coolant temperatures remain stable during spirited driving or stop-and-go traffic, reducing the risk of heat soak that can sap engine output. The material also resists corrosion in high-temperature environments, extending service life and reducing maintenance. The thin wall design of the core maximizes surface area for efficient cooling without adding unnecessary bulk. This balance of properties supports both performance and durability in demanding conditions.
Black Epoxy Coating and Bare Aluminum Finish Options
Choose between a polished bare aluminum finish for a period-correct underhood look or a black epoxy coating for enhanced protection against moisture, salt, and road debris. The epoxy option forms a durable barrier on end tanks and fins without impeding heat transfer, while the natural aluminum finish highlights precision machining and weld quality. Both variants share the same core design, so thermal performance remains consistent regardless of appearance. This flexibility allows builders to tailor the radiator to a restoration that favors authenticity or a restomod that emphasizes modern styling. Either way, corrosion resistance and mechanical strength are assured by the underlying aluminum construction.
